一、引言东北主要小麦产区,在过去已进行过农家品种的整理工作,如克华,宾南,兰寿等品种,就是经系统选拔育成的。根据历年表现,这些品种虽对不良环境抵抗力强、繁茂,穗大和具有耐雨性,但不抗锈,易倒伏、种粒小、软质和出粉率低等缺点,因此这些品种现已被“合作号”各品种所代替。“合作号”各品种虽具有一定优点,但不适于机械栽培,且为耐锈品种,故产量亦不稳定另外直接利用从外国引入的品种,虽然给过去生产上解决了一定的问题,但还存在 I. INTRODUCTION The major wheat producing areas in Northeast China have in the past carried out finishing work on varieties of peasants, such as Kehua, Binnan and Lanshou, which have been bred through systematic selection. According to the performance over the years, although these varieties of resistance to adverse environmental conditions strong, lush, spike and has rain, but not rust, lodging, small seeds, soft and low powder yield shortcomings, these varieties have now been “Cooperation No.” The variety instead. Although the “Co-operative” varieties have certain advantages, they are not suitable for mechanical cultivation and rust-resistant varieties, and therefore the yield is not stable. In addition, the varieties introduced from foreign countries are directly used, and although certain problems have been solved in past production, exist
